“…Sometimes the reaction is effected in acid solution; biphenyl was t8hus obtained in 25-37 per cent yield (131) and 3-nitrobiphenyl in 3 4 4 2 per cent yield (252). 3,3-Dimethyl-l-phenyltriazene upon decomposition in nitrobenzene through which hydrogen chloride was bubbled produced a 35 per cent yield of 2-and 4-nitrobiphenyls (131). Perhaps the presence of hydrogen chloride or even acetic acid favors a polar mechanism, but the reactivity of nitrobenzene can hardly be explained on this basis.…”

“…There are reports that describe a Darzans reaction with ethyl bromopropionate followed by hydrolysis [4], an intermediate glycol followed by hydrolysis [5], or reaction with nitro ethane to form an intermediate nitrostyrene followed by reduction with elemental iron [6]. The conversion of piperonylacetone to MDMA is discussed in section 2.3.4.…”

“…Acid decomposition of l-aryl-3,3-dialkyltriazenes under mild conditions has been reported. 16 We believe that phenol groups of 4 ionize in the presence of moisture to form protons which subsequently decompose the triazene groups. Compounds 4 in DMAc solutions containing an excess of potassium carbonate, however, were stable at 80°C for days as indicated by their 'H-NMR data.…”

Self‐crosslinkable poly(arylene ether)s 6, and 8, containing pendent triazene groups were prepared by nucleophilic substitution reaction of poly(arylene ether)s 5, and 7, respectively, with 1‐[4‐(4‐hydroxyphenoxy)phenylene]triazenes, 4, in the presence of potassium carbonate in N,N‐dimethylacetamide. A series of triazenes 4 containing various substituents have been synthesized. Self‐crosslinkable polymer 6e containing phenyl‐substituted triazene pendants can be crosslinked at 215°C, which is about 40°C lower than the glass transition temperature of the virgin base polymer 5. The degree of crosslinking can be tailored by varying the concentration of the pendent phenylenetriazene groups in the polymer. After curing, the flexible polymer films (ca. 10 μm thick) exhibit high gel contents, increased glass transition temperatures, improved resistance to organic solvents, and little change in dielectric constant and thermal stability. These self‐crosslinkable poly(arylene ether)s are potential candidates for electronic applications. © 1994 John Wiley & Sons, Inc.
